Queen of Hearts 2019 / Denmark's explicit Oscar submission

This Danish film which was the country’s submission to the Oscars is about a delicate subject. A lawyer who specializes in defending children, and who is used to developing closeness with her clients including meeting with them in her home, starts having an affair with her teenage step-son.

There is inherent tension to this obviously very explicit plotline: how would a serious, non-erotic (or not-only-erotic) movie like this one portray such attraction. And of course, afterwards, what are the implications?
